Existing tracfone customer can get 10k reward points by adding a line and keeping it active for 60 days.
https://rewards.tracfone.com/add-line
Points should be worth about $100 when they can be redeemed starting sometime at the beginning of next year. Should be able to buy a 1 year service card with that for example.
If you are not a customer then use a referral from the referral thread to sign up for 5000 points eg
https://www.nthcircle.com/forum/general/76-referral-links-allowed-in-this-thread-only-hungryghost?start=130#50117
and then you can add another line to get the 10k points.
Could work well with this $99 2 phone pack :
